Financial Advisor

As a financial advisor knows, it is important to manage your finances but also your health for the future. With the ability to cleanse the blood of toxins and unhealthful compounds, the kidney is a true champion of the human body. Due to the importance of this organ, it’s crucial for all of us to protect our kidneys.

This is especially true for seniors. According to the CDC, nearly 40% of those over aged 60 have impaired kidney function. Thus, it’s important for seniors with impaired kidney function to follow a renal-friendly diet.


  1. Red Grapes

Red grapes and their seed extract have a component called resveratrol, which can prevent kidney dysfunction. These fruits also are filled with the antioxidants and anti-inflammatory properties to protect the kidney as we age.

  1. Egg Whites

While eggs are a great source of protein, the egg yolk has high amounts of phosphorus, which is not renal-friendly. In contrast, egg whites are easily digestible, renal-friendly, and remain a formidable source of protein.

  1. Radishes

Like egg whites, radishes are low in phosphorus. They are also relatively low in potassium, making them a renal-friendly addition to any senior diet. Even more so, these crunchy vegetables are high in vitamin C and loaded with flavor.

  1. Cabbage

Cabbage is a true catchall vegetable. It’s low in sodium, phosphorus, and potassium, making it incredibly renal-friendly. It also is chock full of fiber, which plays a crucial role in keeping senior digestive systems running efficiently.

  1. Cauliflower

Another great source of fiber, cauliflower provides a nutritious boost to any renal diet. It’s low in potassium, and high in good nutrients like vitamin C and vitamin K. While the low potassium is gentle on the kidney, the aforementioned vitamins work together to boost the immune system and fight free radicals.

  1. Turnips

While many other winter squashes are high in potassium, turnips are much more renal-friendly. As root vegetables, they can be boiled and mashed, creating a kidney-friendly swap for holiday dishes.

  1. Bell Peppers

While bell peppers are incredibly high in nutrients like Vitamin C, they are surprisingly low in potassium. Also low in sodium, bell peppers are a flavorful vegetable that can brighten any renal diet.

  1. Arugula

For a leafy green, seniors should supplement potassium rich spinach or kale for arugula. This wild green is both low in potassium and rich in nitrates. These have been shown to help maintain low blood pressure, which is crucial for those protecting their kidneys.
